摘要： The present disclosure discloses a method for transmitting an uplink measurement reference signal. The method is applied to a network-side device and includes the following operations: first, receiving, by the network-side device, an uplink measurement reference signal sent by user equipment, where the uplink measurement reference signal carries downlink interference information of a downlink channel of the network-side device; and then, performing downlink interference estimation on the uplink measurement reference signal, to obtain the downlink interference information. Compared with the prior art in which a base station cannot obtain downlink interference information of a downlink channel used by user equipment, in the present disclosure, the network-side device can effectively schedule the user equipment based on the downlink interference information, thereby improving scheduling efficiency, and improving data transmission efficiency of the downlink channel.

摘要： A mobile station connected to a multi-carrier cellular communication system having a plurality of sub-carriers. The sub-carriers are classified into K frequency sub-bands, channel state information (CSI) of the frequency sub-bands is represented by matrices Wi (i=0 . . . K−1), where K is an integer greater than 1. The mobile station determines a first sub-index k1 for the K matrices W1 (i =0...K -1), and a second sub-index k2 for each one of the K matrices Wi (i=0 . . . K−1). The first sub-index k1 is common for all frequency sub-bands, and the second sub-index k2 is specific for the indexed matrix that corresponds to one frequency sub-band. The mobile station reports to a base station of the multi-carrier cellular communication system the first sub-index k1 and at least one second sub-index k2.

摘要： The present invention provides a signal sending apparatus, a signal detection apparatus, a signal sending and detection system, a signal sending method, and a signal detection method. The apparatus determines a time unit that is in each time window and that is used to transmit a synchronization signal, and transmits the synchronization signal in the determined time unit in each time window. Therefore, a synchronization signal is always located in a time unit that has a fixed location in each time window, so that a device at a receive end needs to perform detection only in a fixed time unit in each time window, thereby reducing complexity of designing and detecting the synchronization signal.

摘要： In a process by user equipment (UE) to determine a control channel resource, the UE detects a downlink control from a base station. The downlink control channel carries scheduling information of a downlink data channel and comprises multiple control channel logical elements that correspond to the UE and are mapped to one demodulation reference signal (DMRS) antenna port. The UE acquires antenna port information of the DMRS antenna port, an offset, and sequence number information of the control channel logical elements corresponding to the UE, and determines, according to the acquired information, a first control channel resource for sending acknowledgment (ACK)/non-acknowledgment (NACK) information with respect to the downlink data channel corresponding to the downlink control channel.
